ARCHIBALD JOHN MOCALLUM, OF EAGLE HARBOR, MiCHIGAN.

RAILWAY-TIE.

Specification of Letters Patent.

Patented. March 13,1908.

Application filed August 7,1905. Serial Nu- 273,150-

To all whom it may concern:.

Be it known that I, ARCHIBALD JOHN Mc- CALLUM, a citizen of the UnitedStates, residing at Eagle Harbor, in the. county of Keweenew and Stateof Michigan, have invented new and useful Improvements in Railway- Ties,of which the following is a specification.

My invention relates to railway-ties, and has for its object to providean improved metal tie, together with novel means for tastening the railsthereto.

In the accompanying drawings, Figure 1 is a plan view of the tie, butnot showing the rails in position. Fig. 2 is a central longitudinalsectional view with the rails in position. Figs. 3,4, and 5 aretransverse sectional views on the lines A B, C D, and E F, respectively,of Figs. 1 and 2. Fig. 6 is a plan view showing a modification adaptedfor a curved rail. Fig. 7 is a central longitudinal sectional view ofFig. 6. r Fig. 8 is a central sectional view showing a modificationadapted for double rails, .as at switches, &c.

Referring specifically to the drawings, the tie is indicated at n, beingmade of steel or other suitable metal. It is hollow, being substantiallyarch-shaped in cross-section and has at. the bottom inwardly-extendinghorizontal flanges 0. Near the ends of the tie. and formed integraltherewith are boxes a, which are open on top and receive the blocks 1)whereby the rails are fastened to' the tie.'

The blocks serve as rail-chairs and are formed on top with a groove 6,in which the rail is seated, and also flanges 6 extending over thebase-flanges of the rail. The block b is also formed with a lateralextension (1, which ishook-shaped and projects through an opening (1 inthe top Wall of the tie and engages a boss e, formed on the under sideoi the top wall of the tie. The object of this extension is to hold theblock in position. The top of the box a is formed withoutwardly-extending flanges a, between which flanges and the block b areplaced cushions f and g, made of rubber or other elastic material. Asimilar cushion h is also placed in the bottom of the box, on whichcushion the bottom oi" the block rests. The cushionsfand g are slightlythinner than the cushion h, the idea being to have and retain the mostelasticity at it. At

the bottom of the boxes a are holes m for the piece y, extending overone/of the base-flanges of the rail and having a shoulder Z', receivinga bolt l, which is screwed into the block for securing the piecethereto. This construc tion is intended for curved rails.

in the modification shown in Fig. 8 the groove 7/ is made sufficientlywide to receive two rails, as at switches, 84c. Between the rails andfitting on the base-flanges thereof is a spacing-block j, which isfastened to the block b by a bolt Z.

The construction. herein described enables the rails to be readily andsecurely fastened, and the cushions ellectivel y prevent jarring andjolting of the cars.

Having thus described my invention, what is claimed as new, andv desiredto be secured by Letters liatent, is

1 The combination with a hollow railwaytie having boxes formed therein,oi rail-chairs fitting in said boxes and having lateral exien sionsengaging under the top of the tie.

2. The combination with a hollow railwaytie having boxes formed therein,of raii-chairs fitting in said boxes and having hook-shaped extensionsengaging under the top oi the lie.

3. The combination with a. hollow rail\\'a tic having bosses formed onthe inside thorool', oi rail-chairs having hooli-slmpcd extensionsengaging said bosses.

in testimony whereof i have si ned mv name to this specification in thepresence. oi two subscribing witnesses.
